Quiero leerme esa novela este fin de semana.

In Spanish, subject pronouns are often omitted because the verb ending already tells you who the subject is.

• quiero = I want
• The -o ending shows it is yo

So Quiero leerme esa novela... is perfectly natural.
You could say Yo quiero leerme esa novela... if you wanted extra emphasis, contrast, or clarity, but in a neutral sentence Spanish usually leaves yo out.

Leerme is leer + me.

Here, me does not mean that you are reading yourself. Instead, it is a very common pronominal use, especially in Spain, that adds a sense of personal involvement or completion.

So:

• leer esa novela = to read that novel
• leerme esa novela = to read that novel, often with a nuance like read it through / get through it / read it for myself

In many contexts, leerse suggests reading the whole thing, or at least approaching it as a complete task.

Yes. With a conjugated verb plus an infinitive, object pronouns can usually go in two places:

• Quiero leerme esa novela
• Me quiero leer esa novela

Both are correct.

In the sentence you were given, the pronoun is attached to the infinitive, which is very common. In everyday speech, especially in Spain, both versions sound natural.

Yes, absolutely. Quiero leer esa novela este fin de semana is correct and natural.

The version with me adds a nuance. It can make the action feel:

• more personal
• more intentional
• more complete

So the difference is roughly:

• Quiero leer esa novela... = I want to read that novel...
• Quiero leerme esa novela... = I want to read that novel through / I’m planning to get through that novel...

The extra me is often hard to translate directly into English.

Esa is a demonstrative adjective meaning that.

Spanish has a three-way contrast:

• esta = this
• esa = that
• aquella = that over there / that one further away

So esa novela means that novel. Which one you choose depends on how the speaker is mentally or physically locating the object.

Because the phrase is built around the noun fin, and fin is masculine.

• el fin = the end
• la semana = the week

In the expression fin de semana, the main noun is fin, so the demonstrative agrees with fin, not semana.

That is why it is:

• este fin de semana

not:

• esta fin de semana

Spanish often uses time expressions without a preposition when saying when something happens.

So:

• este fin de semana = this weekend
• mañana = tomorrow
• el lunes = on Monday

English often needs on or another preposition, but Spanish frequently does not.

That is why este fin de semana is correct, not en este fin de semana in this context.

Usually it means this weekend, and the exact reference depends on context.

For example:

• If it is Wednesday, este fin de semana usually means the upcoming weekend.
• If it is already Saturday, it can mean the current weekend.

Context tells you which one is meant.

This is a very normal Spanish word order:

• Quiero = main verb
• leerme = infinitive
• esa novela = direct object
• este fin de semana = time expression

But Spanish word order is flexible, so you could also say:

• Este fin de semana quiero leerme esa novela.
• Esa novela quiero leérmela este fin de semana. (more marked/emphatic)

The original sentence is neutral and natural.

Because esa novela is a thing, not a person.

The personal a is normally used before specific human direct objects:

• Veo a María.
• Escucho a mi profesor.

But with things, you usually do not use it:

• Leo esa novela.
• Compro el libro.

So esa novela appears with no a.

Not in the usual sense.

A true reflexive verb means the subject does the action to themselves:

• me lavo = I wash myself

But in leerme esa novela, the novel is still the thing being read. The me does not function like I read myself.

This is better understood as a pronominal or aspectual use that adds nuance rather than changing the basic object of the verb.

Yes, if the context makes it clear which novel you mean.

Compare:

• Quiero leerme la novela este fin de semana. = I want to read the novel this weekend.
• Quiero leerme esa novela este fin de semana. = I want to read that novel this weekend.

Esa points to a particular novel and sounds more specific or contrastive, as if the speaker is identifying one among others.

Yes, very natural.

In fact, the use of leerme instead of just leer is especially common and natural in Spain. It sounds conversational and idiomatic. A speaker in Spain might use it very comfortably in everyday speech.

Without me, the sentence is still correct, but with me it sounds a bit more like how people often really speak.
